Health experts warn against sacrificial animals carrying congo virus

ISLAMABAD, (UrduPoint / Pakistan Point News -29th Augst,2016) : Health experts have warned the citizens to be careful against sacrificial animals carrying congo virus ahead of Eid-ul-Azha. According to them, there was a need for creating awareness in public, visiting animal markets, as well as those handling animals leftovers, buyers and butchers. They said that congo fever could become a grave concern if preventive measures are not taken during Eid-ul-Azha.

They advised the citizens to take special preventive measures in these days to protect from carrying Crimean Congo hemorrhagic fever (CCHF). Dr Wasim Khawaja, a public health specialist at Pakistan Institute of Medical Sciences (PIMS) said reducing the risk of tick-to-human transmission people should wear protective clothing like long sleeves or long trousers and wear light coloured clothing to allow easy detection of ticks on the clothes. He said people should use approved chemicals intended to kill ticks on clothing, use approved repellent on the skin and clothing, regularly examine clothing and skin for ticks, if found, remove them and avoid areas where ticks are abundant and seasons when they are most active. Dr Khawaja said in order to reducing the risk of animal-to-human transmission people should wear gloves and other protective clothing while handling animals or their tissues in endemic areas, notably during slaughtering, butchering and culling procedures in slaughterhouses or at home. He added to reduce the risk of human-to-human transmission in the community, people should avoid close physical contact with CCHF-infected people, wear gloves and protective equipment when taking care of ill people and wash hands regularly after caring for or visiting ill people. Medical practitioner at Federal Government Poly Clinic (FGPC) Dr Sharif Astori said the virus is primarily transmitted to people from ticks and livestock animals.

He added human-to-human transmission can occur resulting from close contact with the blood, secretions, organs or other bodily fluids of infected persons.

He said CCHF is a widespread disease caused by a tick-borne virus.

The hosts of the CCHF virus included a wide range of wild and domestic animals such as cattle, sheep and goats. He said animals become infected by the bite of infected ticks and the virus remains in their bloodstream for about one week after infection, allowing the tick-animal-tick cycle to continue when another tick bites.

The CCHF virus is transmitted to people either by tick bites or through contact with infected animal blood or tissues during and immediately after slaughter, he added. He said majority of cases have occurred in people involved in the livestock industry, such as agricultural workers, slaughterhouse workers and veterinarians. He said human-to-human transmission can occur resulting from close contact with the blood, secretions, organs or other bodily fluids of infected persons.

Hospital-acquired infections can also occur due to improper sterilization of medical equipment, reuse of needles and contamination of medical supplies, he added. He said following infection by a tick bite, the incubation period is usually one to three days, with a maximum of nine days. The incubation period following contact with infected blood or tissues is usually five to six days, with symptoms included fever, muscle ache, dizziness, neck pain and stiffness, backache, headache, sore eyes and photophobia (sensitivity to light).

He said there may be nausea, vomiting, diarrhoea, abdominal pain and sore throat early on, followed by sharp mood swings and confusion. After two to four days, the agitation may be replaced by sleepiness, depression and lassitude, and the abdominal pain may localize to the upper right quadrant, with detectable hepatomegaly (liver enlargement).
